摘要:
An adjustable aerosol delivery device includes an active liquid container, a carrier liquid container, a piezo disc mounted with a flexible gasket relative to the carrier liquid container, an oscillator configured to generate an ultrasonic wave that causes the piezo disc to oscillate and transmit the oscillations through the carrier liquid to the active liquid to cause at least a portion of the active liquid to become an aerosol, a bushing fixed relative to the carrier liquid container via a fixing portion that conforms to and mates with an entire perimeter of a fixing section of the bushing, and a fastener extending through the piezo disc housing and into the bushing. The fastener is configured to be loosened or tightened to manipulate a compression of the gasket to adjust a particle size of the aerosol. A pull force of the bushing is greater than a counter force of the gasket.
